19    Description:
20    
21    Snapshot of a significant overhaul of how the trace/debug/profile support
22    is hooked into the system (specifically: Core and SMLofNJ.Internals).

28    Description:
29    
30    Some rationalization of names:
31    
32       structure BTrace -> structure TDPInstrument
33       etc.
34    
35    This is is preparation of using the original back-trace
36    instrumentation for other purposes.  "TDP" stands for
37    Trace/Debug/Profile.
38    
39    The control flag controlling whether instrumentation is on or off is now
40    registered under a different name, so instead of running sml as
41    
42     sml -Cinstrument.btrace-mode=true
43    
44    one has to say
45    
46     sml -Ctdp.instrument=true

52    Description:
53    
54    Made some minor modifications to elabcore.sml to have source regions
55    be propagated more tightly -- resulting in better (i.e., smaller)
56    regions being reported in error- and debug messages.

61    Tag: blume-20041008-cmkw
62    Description:
63    
64    Fixed handling of keywords in .cm files: After seeing "is" the lexer
65    treats subsequent occurrences of "group", "library", "source", "is",
66    "*", and "-" as ordinary identifiers rather than keywords.
67    
68    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
69    is supposed to accept a tool argument called "source", but this did
70    not work because of the clash with the keyword.

76    Description:
77    
78    Assorted cleanup work:
79    
80      - got rid of intstrmap in favor of using the library's
81        hash table implementation
82      - threw out most of the pathnames stuff, as it was not used anyway
83      - simplified tokentable implementation
84      - fixed some minor spelling errors

90    Description:
91    
92    Cleaned up the absyn to reflect the invariant that HANDLE always
93    carries a FNexp as part of the type definition.  This eliminates some
94    superfluous sanity checks at runtime down the road.
95    
96    Some minor cleanup of the btrace code.

102    Description:
103    
104    Added hack to make slave mode work in the presence of the version
105    tool.  (Still, since the master does two passes over the code for
106    CMB.make, the release number gets bumped twice when slaves are
107    attached.  I don't know if this is worth fixing...)

112    Tag: blume-20040930-version
113    Description:
114    
115    * Moved the "version" magic into its own little library under
116    src/system/smlnj/internal.  This avoids expensive reconstruction
117    of a stable src/compiler/core.cm.
118    
119    * At the same time, structure CompilerVersion is now known as structure
120    SMLNJVersion.
121    
122    * Arranged for the version tool to NOT kick in when rebuilding the system
123      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
124      Also, loading the versiontool does not work when rebuilding the system
125      because CM is not properly initialized at that time.

130    Tag: blume-20040929-autoversion
131    Description:
132    
133    Implemented some CM magic to have
134        file src/compiler/TopLevel/main/version.sml
135    generated automagically.
136    The version is taken from two files: config/version and config/release.
137    The first is expected to contain a two-part version number such as 110.49.
138    The second should contain a single number, but it may be missing.
139    
140    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
141    time the version tool is loaded (which is the first time you say CMB.make),
142    then the tool will increment the value stored in config/release every
143    time CMB.make is invoked.
144    
145    The binfile format is now insensitive to anything beyond the first
146    two components of a version number, so bumping the release does not render
147    binfiles incompatible.  Auto-bumping can be used to keep track of versions
148    during development without invalidating existing binfiles.
149    
150    In any case, every CMB.make updates the date information in version.sml.
151    (This is the date that is printed in the banner.)

156    Tag: blume-20040928-controls
157    Description:
158    
159    Some cleanup of the controls code.
160

163    Date: 2004/09/27 22:08:00 CDT
164    Tag: blume-20040927-controls
165    Description:
166    
167    Added two pieces of functionality to the Controls interface:
168    
169    1.   val save'restore: 'a control -> unit -> unit
170    
171       grabs the current value of the control in stage 1 and restores it
172       in stage 2.
173    
174    2.   val set' : 'a control * 'a -> unit -> unit
175    
176       stores the given value into the control in stage 2 (i.e., delayed)
177       but does all error checking in stage 1.
178       (This is for string controls that need to do parse their argument --
179        something that might fail.  In some cases, notably in CM, one
180        already knows the intended argument but wants to delay the actual
181        assignment until a time when error recovery would be more difficult.)
182    
183    Changed the handling of controls in tool arguments to classes "sml" and
184    "lazysml":
185       - use Controls.save'restore as a more robust way of restoring the
186         old value (in particular: without having to re-parse the string)
187       - use controls to handle the "overload" keyword in the init group
188         (I believe this change actually fixes a long-standing obscure bug.)

193    Tag: blume-20040927-lazysml
194    Description:
195    
196    Added a new tool class called "lazysml" to CM's tool chest.  The only
197    difference to "sml" is that compilation is done with Control.lazysml
198    set to true.  A source of class "lazysml" is automatically recognized
199    by a file name suffix of ".lml".
200    
201    In addition to the above feature, the original class "sml" now also
202    supports a tool argument "lazy" which has the same effect.  As a
203    result, the following three lines are equivalent:
204    
205        foo.sml : lazysml
206        foo.sml : sml (lazy)
207        foo.sml (lazy)
208    
209    The setting goes into effect both during parsing and during
210    compilation.  The original setting is restored right after parsing and
211    after compilation, respectively.
212    
213    In addition to all the above, there is also a general mechanism to set
214    ANY of the "controls" that are available at the command line via
215    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
216    apply as well. (In fact, "lazy" is implemented as a special case of
217    the general mechanism.)
218    
219    The .cm file syntax uses a new keyword tool argument called "with".
220    There are several ways of indicating the desired settings:
221    
222        foo.sml (with:parser.quotations=true)
223        foo.sml (with:(name:parser.quotations value:true))
224        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
225        foo.sml (with:(name1=value1 name2=value2 ...))
226        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
227    
228        etc.
229    
230    Another possible abbreviation is to leave out the =v or value:v part
231    if the name refers to a boolean control (in which case the value is
232    taken to be true).  Thus, one could get lazy sml also by saying:
233    
234        foo.sml (with:parser.lazy-keyword=true)
235        foo.sml (with:parser.lazy-keyword)
236        foo.sml (with:(name:parser.lazy-keyword value:true))
237        foo.sml (with:(name:parser.lazy-keyword))

243    Description:
244    
245    Turned message about "emiting long form of branch" off by default.
246    Added a control flag to turn it back on when desired.

255    Melissa O'Neill for providing the code!

260    Tag: blume-20040923-envvars
261    Description:
262    
263    1. Changed definition of type ControlRegistry.registry_tree to
264       include control_info (i.e., the name of the controlling environment
265       variable).
266    
267    2. Added command-line flags -e and -E to print the names of environment
268       variables that can be used to control internal settings.
269       (This uses the new API mentioned in 1.)
